Hi Ed , this is what I use to save this kind of data.
You need to have modified the settings.js for example as shown in Paul subject.
Here is my settings.js
contextStorage: {
default: {
module:"localfilesystem",
config: {
"dir":"/home/pi/global-variables"
}
}
},
You just have to modify the flow to do what you want with it.
Mine proposes you to save the data from the dashboard via HTTP.
I hope this is what you are looking for.
Here is my flow:
